To all whom it may concern.-

Be it known that I, J UNIUS O. MURRAY, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Shoe- Lasting Tools, of which the following is afull,

clear, and exact description, reference being had to the accompanyingdrawings, forming a part hereof.

My invention has relation to improvements in shoe-lasting tools; and itconsists in the novel construction and arrangement of parts more fullyset forth in the specification and pointed out in the claim.

In the drawings, Figure 1 is a perspective showing the application of myinvention. Fig. 2 is a side elevation of the tool, showing the hammer inits released position and a section of a shoe-upper in position to begripped by the jaws. Fig. 3 is a side elevation of the opposite face ofthe tool. Fig. 4 is a combined side elevation and section with parts.

Fig. 10 is a verticalcross-section on line 10 10 of Fig. 9 and corresponding to, the positionof the parts shown in Fig. 7. Fig. 11 is a similar section to Fig. 10,but showing the depending arm of the hammer and the cut-off in aposition corresponding to the parts in Fig. 8. Fig. 12 is a sideelevation of the raceway. Fig. 13 is a cross-section on line 13 13 ofFig. 12, and Fig.'14 is a detail of the cover-plate for the operatingparts.

The object of my invention is to construct a hand-operated tool by whicha shoe may be lasted with a minimum expenditure of time, therebycheapening the cost of manufacture.

As now generally practiced, after passing the shoe-upper over the lastand the placing of the insole upon the bottom of the last, the edges ofthe upper are drawn over the edges of the insole and either permanentlytacked thereto, as is the case of a McKay shoe, or only temporarilytacked, as in turn and welt shoes. To drive the tack, the operatorgenerally places the tack between his lips, where I he can convenientlyreach it; but the placing of the tack from the mouth upon the upper inposition for driving into the insole consumes considerable time whenfigured in the aggregate for the shoe-laster of a large factory. With myinvention the upper is drawn over the insole andthe tack is driven bythe springing of a trigger which releases a spring-controlled hammer,the latter in turn actuating a plunger under which the tack isautomatically fed from a raceway mounted on the tool when the hammer iscooked. The manipulation of the hammer and subsequent springing of thetrigger by comparison with the old method consumes considerably lesstime and makes my invention a specially desirable tool for shoe-lasting.In detail it may be described as follows:

Referring to the drawings, S represents a shoe-last, U the shoe-upper,and I the insole carried by the last. The edge of the upper is adaptedto be pulled over the edge of the insole by the serrated jaws 1 1,forming the short arms of the levers 2 and 3, respectively, said leversbeing pivoted to one another about their medial enlarged portions andforming pincers for the gripping of the shoeupper. The lower edge of thelever 2 is provided at a point slightly in advance of the pivotal screw4 with a foot 5, which scrves as a fulcrum adapted to bear against theinsole while the shoe-upper is being drawn or pulled over the insole,Fig. 1. The body of the lever 2 is suitably chambered to receive theoperating parts of the tool and to be presently described.

The parts are protected by a plate 6, which is provided with a boss 7,entering a corresponding socket of the lever, the boss 7 in turn havinga socket 8 to receive a boss 8 of the lever 3, the screw 4 being passedthrough the several parts and connecting them together, Fig. 6. Thisarrangement serves to remove the strain off the screw 4. That the facesof the lever 3 and the plate 6 may come substantially flush theplate hasformed on it a depression 9 for the reception of the body of the lever,as shown best in Figs. 2 and 6.

Pivoted between the plate 6 and the lever by a p'n 10, supported by saidplate and lever, (t e lever 2 for convenience to be hereinafter referredto as the stationary mem- 2, near the upper edges thereof, and carriedber and thelever 3 as the movable one,) is

a hammer l lever 11, "having a 'terminal'head 11. Adjacent to the headis an adjustingscrew 12, which limits the descent of thehead by comingin contact with the-top edge of the member 2. The end of the short armof the member 2 is provided with a socket 13, through which passes aplunger 14, the upper portion of the socket being enlarged to receive aspring 15, coiled about the plunger and confined between the terminalhead 16' mer-lever to one side of the pivot-pin "10.

The hammeris cocked on the order of a firearm by meansof a trigger 18,pivoted within the chamber ofthe member 2, the nose 19 of the triggerengaging a shoulder 20 on the hammer, the engagement being madepositiveby the resilient action of a small spring 21, located in asuitable cavity or socket formed for its reception in the member 2. Byspringing thetrigger (seedotted position in Fig. 4) the hammer isreleased, and the head 11 thereof 'is forcibly driven against theplunger 14, whiclrin-tiu'n drives the tack t through the upper and intothe insole to a depth depending on the character of shoe-to the fulldepth 'for 'a McKay shoe and only partiallyinto the insole for a turnandwelt shoe. This depth, as'before stated, isrcgulated bythea'djustment'oi the screw 12011 the hammer, thepositionofthe screwdefining the extent to which the hammer-head shall descend.

The tacks are fed to the plunger by the following mechanism: Secured tothe *mem: her 2 on'the' opposite side from the member 3 is a'raceway 22,thesame being connected to the tool by a screw 23, passed through'a lug24 thereof, Figs. 12, 13, the'raeeway being in the form'of a curvedchannelhaving a surmounting hood or cover 25, secured at intervals tothe sides of the raceway by connecting members or brackets 26, brazed tothe sides, Fig. 13, theheads'of the'tac'ks 't spanning and resting onthe edges of the channel and. sliding downthe same, Fig. 12. Thedelivery or discharge end oftheraceway communicates with a'feed-tube 27(closed at the bottom) through the wall thereof, the tube 27being-curved"toward the socketin whichtheplunger 14 is mountedfiFig. 7,and into which it discharges-itstac'ks from the side. Secured rigidly tothe memberQ, just above'the raceway, is one' end of'a'cut-oif-orspring-arm 28, which curves downwardly, the free end thereof beingprovided with a block 29, which is free to pass into the tube 27 throughthe side of the latter and, under conditions to be presently referredto, intercept the tacks coming down the tube. Formed on the arm 28 onthe face adjacent to the member 2 is a cam or knob 30, with which isadapted to engage a corresponding cam or knob 31 on an arm 32, dependingfrom the hammer 11 and passing between the member 2 and the spring orcut-ofi' 28. When the device is cocked, Figs. 1, 4, 8, 11, the knob 31is out of engagement with the knob 30 and jaws 1 1, the fulcrum 5being-used asa'lev-' erage to pull theupper ovei the insole. The moment"the hammer descends 'to drive "the tack the cam 31 engages thecam 30,thus forcing the spring-arm 28 away from the member 2 sufficiently toretract the intercepting-block 29 from under thebottomtack in the tube27, Fig. 7, this movement releasing the series oftacks and allowing the=bot-' tom one-to drop on the bottom of the tube and come'in line withthe block and there be 'l rictionally held against the now.fully-descended plunger, Figs. 3, 7, 10. The moment, however, the deviceis cocked againto the position shown in Fig. 1tlie-spring 15retracts theplunger, and the hammer being pulled upward will retract the knob 31away fromthe knob 30, allowing the cut-off 28 'to spring back toward themember 2 and force the block 29 thereof back to :the position shown inFig. 8, thus again s'hoving'the last tack under the plunger, whereitholds it frietionally against the wall of the 'soeke't 13. When oneraeeway is empty, a fres'h raceway may-be immediately attached'by simplyunscrewingthe screw 23.

In the operation of the device the=operator places the foot -5 againstthe insole, *then gripping the edge of the upper-draws the sameover theinsole. He canthenwith his thumb-pull down on the rear end ofthe'hammer, which-cocks it, thus allowing the last tack of'the series tobe shoved-by the block 29-under'the plunger. Then bypulling thetriggerwithhis forelmger thetaek is driven into the upper and insole,and the-next tack ofthe series is brought into position opposite theblock 29 to be again shoved under the plunger with the next cockingofthe hammcr.

With my device a very rapid lasting ofthe shoe can be efiected, with nowaste oftacks By springing the tri er, and thus IIS and with noinconvenience whatsoever. I may of course depart in a measure from thedetails here shown Without in any wise affecting the nature or spirit ofmy invention.

Having described my invention, what I claim is In a shoe-lasting tool, apair of pivoted intersecting members having gripping-jaws, a footprojecting from one of the members and serving as a fulcrum, aspring-actuated trigger-controlled hammer pivoted to the same memberabove the pivotal connection between the members, a spring-controlledplunger at one end of the same member actuated by the tripping orrelease of the hammer, a curved raceway, a tube into which the racewaydischarges, a cut-off for the tacks having a terminal block adapted tointercept the tacks descending toward the bottom of the tube and pushthe bottom tack under the plunger upon the cooking of the hammer, and torelease the succeeding bottom tack of the series and allow the same todescend to the bottom of the tube upon the springing or release of thehammer, substantially as set forth.
